TAUNTON — A Taunton woman was among the group of runners who were joined by survivors of the Boston Marathon bombing to take the final steps in a coast-to-coast relay on Sunday.

Elizabeth Dias, who last year was sitting 600 feet away from the bomb blasts, took part in the second edition of the One Run for Boston to help victims of the marathon bombing. She took part in the first iteration of the charity relay last year to help raise money for the One Fund. This time she helped bring a baton down the final stretch after it was carried across 14 states from California to Massachusetts, ending at the finish line of the Boston Marathon on Boylston Street.

“I thought this year maybe it would not be as emotional as the first one, which took place two months after the bombing, but this one was really special,” Dias said Sunday night. “We ran and stayed together as a unit, and 50 yards from finish line several survivors walked in front of us as we crossed. We had so many people out there cheering for us. It was unbelievable. It was an incredible feeling.”

Her section of the One Run relay, starting near Harvard, acted as a warm-up for Dias, who is running in the Boston Marathon next Monday. It will be her first marathon.

During the relay, she met Carlos Arredondo, the man who helped bombing victim Jeff Bauman during the chaos after the blasts at the finish line. “It was incredibly powerful and moving,” Dias said.

The One Run for Boston raised about $93,000 for the One Fund last year, Dias said. But this year, participants helped raise $430,000 for the One Fund.

Dias said she originally got involved with the One Run for Boston after learning about the event on Facebook and making friends online with others who were involved with the relay. Three British runners who heard about the tragedy organized the cross-country relay. From there, she met friends who provided her an open spot in the Boston Marathon for this year.

“When I looked into it, it was a very grassroots campaign to raise money for the survivors of the marathon,” said Dias, 48. “There wasn’t a lot of information. I basically looked it up and thought it was an amazing thing. It sounded like a crazy idea, but fun. But it really grew through social media. It became a huge event last year. When it took place the first time, two months after the bombing, everyone was still sort of reeling from that. It ended here at 1 a.m. last year, and it was very emotional. This year it ended during the day and the crowds were big, cheering us on. It was really special.”
